This invention relates to tarpaulin clamping mechanism for hatches andxparticularly to battens and clamping means'therefor for firmly clamping the edges ofthe tarpau'lin` about the combing of the hatch.

The object of the present invention is to provide tarpaulin clamping means for hatches whereby the battens are firmly held in place against the edges of the tarpaulin to` hold it uniformlystretched in position over the hatch cover and prevent it from becoming4 dislodged. y

In the embodiment herein shownthe hatch" combing is provided with a vplurality of clamps forming stops and clamping means for battens which are adapted to engage the edges Vof the tarpaulin .and clamping them neatly and firmly against the sides ofthe combing, thc arrangement of the clamping means being such that the battens are forced downwardly and inwardly toward the combing and stops thereon" to insure the proper positioning of the hatten on the one hand and to insure a firm clamping means along sub-yl .stantially the upper edge of the batten for holding the tarpaulin in place. The foregoing and other features of the invention will be brought out in the following description, drawingsand claims.l

Referring to the drawings, Fig.` 1 is a sectional view through a hatch cover and comb- Y ing illustrating the clamping and tarpaulin` holding means; Fig. 2 is a front elevation; and Fig. 3 is a section. p p

In the arrangementishown 1 represents the hatch combing vprovided .with the usual cover 2. The tarpaulin `3 extends over the cover and down the sides of the combing 1 and must be held in place along its edges against the 40 outer face of the combing.

Secured to the outer face of the combing i t are a plurality 4of flanges 4 each carryinga threaded stud 5. These flanges also carry r stop pads 6, there being two shown. These 4* stop pads are symmetrically disposed on either side of the stud 5 and are preferably arranged just below the same asshown Vin Fig. 2. They form stops for the lower ends of the clamps as will appear. 'Engaging around each of the studs 5 is an elongated eye stare-S. i

VCLAMP formfinglthei lower part of'lvaV e; comprisingjthe shank V8 "and a downwardly Vextending'hooknoseQ adapted toijengage the upper edge of thebatten fr The'battens. around thehatch are 'adapted to rest upon 551 the stops formed by the upper straight edge of theflange 4, as shown in Fig. 2.V Each of the clamps at the upper end of the'eye and adjacentthe shank 8 is provided with an arc shaped tapered camf1-1 adapted to engage the 60 y internal surface of a conical slrirt12 form-ff ing a part of a clamping nut 13 threadedonto one of the studs 5. This nut is provided witl i' a suitable wrench orother hold 14:.

In'practice the tarpaulin is spread nicely ,65 over the `cover with marginal portions extend- 'if ing down the sides of the cover about the hatch combing. The marginal portions Vare Y then drawn inward and engaged by the batV- f tens which are located in place back of the l 79 clamps, the hook portions 9l of the clamps'fr engaging thev upper edges of the battens. The operator then tightens all of the clamping nuts causing the batten clamps to be forced inward until the lower portions of the eyesA 7 engage with the stop pads 6 when the upper f1' ends of the clamps will be thrown inward i .toward the hatten and th-e combingand continuedrotation of the Aclamping nuts through the conical skirt and the cams 11 draw all of SG the hoolrsdownwar'd thus forcing the battens inward toward the combing and downward toward the studfflanges thereby firmly seating the battens in place against the tarpaulin and clamping it tightlyagainst the'hatch 55 combing. In this way the tarpaulin is lirmly held in place -andcannot become loose at any i point with'obvious ydisastrous results, such asallowing wind to play havoc with the tarpaulin and otherwise producing an unsightly covering overthe hatch.

Having described my invention, I claim:

1. In combination with ai hatch combing, hatten stop means arranged thereon, loose battens engaging the stop means and a pluralf ity of battenrclamps eachhaving a single hook engaging'the outer face and upper edge of the batten, clampv stop meansV for resisting the inward thrust of the clamps to force their upperends toward said hatten, Aand mi irai] v means eng-ging said elamips'andexerting inl `ward and downward thrust'thereon.
